A wintry mix of rain, snow and sleet affected Southwest Lower Michigan from late morning to mid afternoon Sunday. This was followed by thunderstorms that dropped a large amount of pea-sized hail across much of Ottawa, Allegan, and Kent Counties, making for slippery travel and minor nuisance flooding due to clogged drains. Figures 1 through 3 show the track of the storm through Kent County, including the Grand Rapids area. The size of the hail, which can be seen in Fig. 4, was very consistent across the area.
Fig. 1. Storm moving east across Ottawa County. Dark red and white colors are associated with hail.
Fig. 2. Hail near its heaviest in downtown Grand Rapids around 150 PM EDT.

Fig. 4. Typical hail size associated with the storm.
More storms formed late in the evening hours on Sunday evening, and continued into the overnight hours. These storms produced some small hail once again, and produced some decent rainfall through the night on Sunday night.
Below is a radar estimate of the rainfall/melted snow that fell from Sunday morning through Monday morning. The heaviest rainfall occurred in a corridor from southern Oceana county south of Pentwater, to the Mt. Pleasant, Reed City, and Clare areas. These locations saw between 1.5 and 2.5 inches of rainfall/melted snow fell. Some local areas saw just under 3.0 inches of precipitation. Some flooding occured in Mecosta county as standing water was over a few roads in the county, and one road partially washed out.
